Your goal is a 6-phase interleaved boost from 48–58 V to 70–75 V at 3.6 kW, 300–500 kHz, with remote on/off. I’ve prepared a plan to implement it. Steps:
- Define requirements and interleaving strategy, protections, and enable behavior.
- Size/select power stage (inductors per phase, FETs/rectifiers, gate drivers, sensing, snubbers).
- Choose controller (multi-phase analog vs digital), implement soft-start, current balance, faults, enable.
- Design filters and layout rules, plan thermal/EMI.
- Capture schematic, select parts, connect, simulate, then PCB layout and reviews.

Your goal: 6-phase interleaved boost, 48–58 V in to ~72 V out, 3.6 kW, 300–500 kHz, 96% target, 3.3 V enable. I’ve prepared a plan:
- Freeze specs: per-phase f_sw, ripple targets, UVLO/OVP/OCP/OTP, 3.3 V enable and soft-start.
- Choose architecture/control: 6-phase interleaved, current-share, per-phase sensing, fault latch.
- Size power stage: inductors (≤60% of Imax, ≤90% of Isat; ripple 20–40%), FETs/rectifiers, drivers, snubbers, IO caps, EMI filter.
- Capture schematic and select parts; implement enable/protections; generate BOM.
- Simulate (transient/efficiency/thermal), then PCB layout and reviews.

- A generic fixed capacitor ideal for rapid circuit topology development. You can choose between polarized and non-polarized types, its symbol and the footprint will automatically adapt based on your selection. Supported options include standard SMD sizes for ceramic capacitors (e.g., 0402, 0603, 0805), SMD sizes for aluminum electrolytic capacitors, and through-hole footprints for polarized capacitors. Save precious design time by seamlessly add more information to this part (value, footprint, etc.) as it becomes available.
